A Flexible Holomorphic Embedding Method for Integrated Gas and Electricity System

Energy flow calculation is the basis of system planning and optimal scheduling. However, the traditional energy flow calculation method has the problems of sensitive initial value selection and slow convergence in complex scenarios. In this paper, an energy flow calculation method based on flexible holomorphic embedding in the Integrated Gas and Electricity System is proposed. Based on the construction of a flexible holomorphic embedding model, the power series coefficients of the state variables of the system are recursively solved, and the energy flow distribution of the system is obtained. Simulation experiments verify the effectiveness of the proposed algorithm, and show advantages in computational efficiency and convergence performance compared with Newton Raphson method.
